Kua tāruatia ki te papatopenga
\Delta =4x+5
Pahekotia te 1x me 3x, ka 4x.
4x+5=\Delta
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
4x=\Delta -5
Tangohia te 5 mai i ngā taha e rua.
\frac{4x}{4}=\frac{\Delta -5}{4}
Whakawehea ngā taha e rua ki te 4.
x=\frac{\Delta -5}{4}
Mā te whakawehe ki te 4 ka wetekia te whakareanga ki te 4.
\Delta =4x+5
Pahekotia te 1x me 3x, ka 4x.
